IPC: G01R31/12
Filed: 1978-11-22
Abstract: PURPOSE: To enable to measure only the partial discharge pulse for the object with the corona measuring unit singly, by erasing the external noise produced at the part other than the object in the partial discharge test circuit in balancing operation.  
     CONSTITUTION: As the means rejecting external noise, the variable impedance element 20 adjustable to the impedance equal to the high impedance element 16 and the balancing section 28 including the pulse transformers 23 and 24 are provided. Further, high frequency cable 26 and the corona detector 27 are connected to it. Thus, the voltage is reduced to external noise and the output voltage of the pulse transformer can not be measured with balancing operation.

Filed: 1992-06-04
Abstract: PURPOSE:To provide a solid-state image pickup element in which a sensitivity, when a diaphragm is arranged, is satisfactory by specifying a position relation between a microlens and a photoelectric conversion element. CONSTITUTION:When a luminous flux having an apex angle theta decided by the maximum diameter of the diaphragm and a distance between the diaphragm and a microlens 40 is used as an incident light to the lens 40, the photoelectric conversion element is positioned at a position equivalent to a distance L from the lens 40 where the minimum luminous area can be obtained on a face vertical to the optical axis of a transmitted light from the lens 40. Thus, when the incident light quantity decided by the diaphragm is minimum, a light converging intensity to the photoelectric conversion element by the lens 40 can be especially improved compared with the other cases. Therefore, even when the incident light quantity is minimum, the sufficient sensitivity can be obtained.
